Colin R. Woods,L. Britnell,Axel Eckmann,Ruisong Ma,Jianchen Lu,Haiming Guo,Xiao Lin,Geliang Yu,Yang Cao,Roman V. Gorbachev,Andrey V. Kretinin,Jaesung Park,Jaesung Park,Leonid Ponomarenko,Mikhail I. Katsnelson,Yu. N. Gornostyrev,Kenji Watanabe,Takashi Taniguchi,Cinzia Casiraghi,Hong-Jun Gao,Andre K. Geim,Konstantin S. Novoselov +21 more
TL;DR: In this article, the authors reported a commensurate-incommensurate transition for graphene on top of hexagonal boron nitride (hBN), where areas with matching lattice constants are separated by domain walls that accumulate the generated strain.
Journal ArticleDOI
Ternary site preference energies, size misfits and solid solution hardening in NiAl and FeAl
TL;DR: In this paper, the electronic structure of NiAl and FeAl doped with ternary additions in both sublattices has been investigated with the local density linear muffin-tin orbital (LMTO) method.
Journal ArticleDOI
First-principles total-energy calculations for planar shear and cleavage decohesion processes in B2-ordered NiAl and FeAl.
TL;DR: It is found that dislocations in FeAl show a strong tendency for splitting into two superpartials, in contrast with NiAl, and estimates of the Peierls stress yield the correct preferred slip systems for NiAl.
Journal ArticleDOI
Magnetism and local distortions near carbon impurity in $γ$-iron
D.W. Boukhvalov,D.W. Boukhvalov,Yu. N. Gornostyrev,Mikhail I. Katsnelson,Alexander I. Lichtenstein +4 more
TL;DR: It is shown that the carbon impurity creates locally a region of ferromagnetic ordering with substantial tetragonal distortions in gamma-iron, which is in very good agreement with experimental data.
Journal ArticleDOI
Effect of composition on antiphase boundary energy in Ni 3 Al based alloys: Ab initio calculations
Oleg I. Gorbatov,Oleg I. Gorbatov,I. L. Lomaev,Yu. N. Gornostyrev,Andrei V. Ruban,David Furrer,Vasisht Venkatesh,Dmitri Novikov,S. F. Burlatsky +8 more
TL;DR: In this article, the effect of composition on the antiphase boundary (APB) energy of Ni-based alloys was investigated by ab initio calculations employing the coherent potential approximation, and the calculated APB energies for the {111} and {001} planes reproduce experimental values of the APB energy.
